OPERATING INSTRUCTIONS
1. Check PVC Heating Blanket for cuts, tears, burns, exposed wires, frayed
edges or frayed cords. DO NOT use if any of these conditions exist.
Blanket has no serviceable parts.
2. Place the blanket under the PVC
conduit where the bend is to be
made. (See Figure 4a).
3. Begin to wrap the PVC Heating
Blanket around the conduit.
(See Figure 4b).
Continue to wrap the blanket
snugly around the PVC conduit
and secure the blanket in place
with the velcro straps. The blanket
should overlap the thermostat
housing. (See Figure 4c).
4. Next, with the blanket secure
around the PVC conduit, support
the PVC conduit as shown in
Figure 4c. Two 4"×4" pieces of
wood are recommended. This is
to prevent damage to the heating
blanket during the heating process.
5. Plug in the PVC Heating Blanket.
As the PVC conduit heats, you can
check for softness by pressing on
the sides of the blanket. The PVC
conduit is ready to bend when it
becomes very flexible. UNPLUG
THE PVC HEATING BLANKET and
unstrap the velcro straps.
